Abstract
In this paper, we report on a peak power evaluation system using a two-photon absorption (TPA) detector. An InGaAs/GaAs-based detector, which has the band gap of 980nm, is used for the TPA detector. We have observed that the peak power of the pulse, which was generated by a Mach-Zehnder modulator (MZM), became maximum value when the chirp was completely compensated.
